APPARATUS'FOR TREATIN LIQUIDS.

Specification of Letters Patent.

Patented May 26,1908.

Application filed December 1, 1906. Serial No. 345,919.

To all whom it may concern:

Be it known that I, WILBUR ALSON HEN DRYX, a citizen of the UnitedStates, residing at Hotel Metro ole, in the city of Denver, in thecounty of llhnver and State of Colorado,

have invented new and useful Im rovements in A aratus for Treating Liquis, of which the f llowing is a specification.

The object of this invention is to provide an apparatus for treatingliquids and separating solids therefrom the apparatus is moreparticularly intended for separating the metallic values frommetal-bearing solutions.

One form of the apparatus is shown in the accompanying drawin wherein:

Figure l'is .a vertica section, partly'in elevation, of a form ofdevice'adapted for the separation ofgold and silver from their cyanid or othersolutions; and Fig, 2 is a vertical sect-ion of the feed device on line2--2 of Fig. 1. I

in the drawing, 1 represents atank which may be of sheet metal andadapted to with stand a considerable internal ressure of liquid; 2, 2are filter cells vertica y disposed in the tank, each cell having abottom outlet 3 provided with a valve 'orcock as shown, all. ofsaidoutlets preferably discharging into a common conduit 4 for thefiltered liquid. As shown each filter cellflcomprises an'open frame 5having lateral filtering walls 6 of. canvas or other suitable material,and a filling 7 of material such as cocoa-matting or the like which isadapted to sustain the filter Wallswhile providing a free passage forthe solution. I 1

Thetanli is'shown as surmounted by a casing 10 containing a revolubleshaft 11 mounted inu'oper and lower bearings 12, 13, and carryinghelical agitating blades 14; as shown the-casing is providedwithstiationary bafies 15,, the combined effect of the blades and bafiesbeing to eiiect a thorough agitation of. the material traversing thecasing, and the, recipitation of the greater-portion of the va ues thehelical blades serve also as a ump to establish a'current of the liquidor so utioh through the ipe 8 commumcating' with thetank 1 and t edesired pressure of the same in the-tank. An inlet pipe 16 is arrangedadjacent the lower end of the-casing. 17 is a hopper ada ted to containthe precipitating agent an to effect its regulated discharge into themetal-bearing solution cohveged by the pipe'16. The hopper 17 is provied with an inclined bottom 18 and a lively, an are connected by a belt29;

central discharge pipe 19 leadin to the pipe 16; a; recessed feed-wheel20 0 usual construction is mounted in the discharge aperture of thehopper upon a shaft 21. By rotation of the recessed wheel measured orregulated charges of the material in thehopper are discharged into thestream of solution in the stood. The construction of the feed-hopper isclaimed in my copending application Serial No. 344,058, filed November19, 1906, I As shown it is provided with an'agitating del vicecomprising upper and lower s rocket 10 wheels 22, 23 carrying a s rocket0 sin 24 which asses through the hody of material the hopper and by itsmovement thoroughly ag1tates the same and revents arching or otherinterruption of t e feed. The sprocket wheel 23 is loosely mounted on as aft 25, thes rocket 22 being rigidly mounted on'the she t 26. Scod-pulleys 27 28 are secured u on the she ts 26 and 21, res at? emechanism may be driven by a pulley 30 on shaft 26, or otherwise. Bymeans of the speed'pulleys,'and also by blocking one or more ofthe-recesses in the wheel 20, a close regulation of the rate of feed ofthe precipitating agent may be secured.

Assuming the apparatusto. be used for precipitating gold and silver froma cvanid solution, the operation is as follows: Zinc dust'or fume isplaced in the hopper 1-7 and pipe 16 as will be readily under-' themetal-bearing solution is admitted to the" pipe 16. By operation of thefeed-device in the ho per zinc'dust is fed to the flowing solution 1nthe proportion'required to preci itate the meta-lie values therein or inslig -t excess of such proportion. In the casing 10 the solution andreci itant are thoroughly commingled by t 1e '0 edes and bafiies and thegreater portion of the metallic values is separated. The liquid carryingthe precipitated values and undissolved precipitant in suspension passesto the tank 1, from which the clear solution flows through the filtercells to the conduit 4, to be returned to the leaching vats after anyrequired treatment for the restoration of its solvent power.

The undissolved residue of the precipitant, together With tl eprecipitated values, collects upon the ca vas or other filtering medium6 in the form of a porous coating -through which all further portions ofthe liquid must pass: in this coating the solution is brought intointimate contact with the undissol'ved zinc and my gold or silver whichmay remain in solution is separate After a sufficient quantity ofprecipitate has been collected iiie liquid contents of illfitiifiii arei- SCll. rged and costing dislodged from the iilter, as by u strezuu ofWater admitted through the eloiigaied iuuid-iiold l, and tile metalsinildrswn through valved outlet 9 and refined iii suikublc manner.

It will iiced airs; the discharge pigie 8 from the i0 ext-ends nearly tothe so?- tom of the tsnlzl and subs'ta. tiolly central illereiii. Thepurpose of this arrangement "5o yrevent any considerable roportiou ofzinc or preoipilsled values from dcposit'ins on tile bottom oi Elietank, and to sue to fo i a cake or deposil upon the torisufi'accsussbuve described.
